TPU (Thermoplastic Polyurethane Elastomer)
TPU - Thermoplastic Polyurethane Elastomer Thermoplastic polyurethane elastomers exhibit excellent abrasion and wear resistance and high tensile and tear strengths. TPUs are tough, durable, easy to clean and well-suited to applications that demand the elasticity of rubber combined with high stability. In addition, the inherent translucency of these products makes it easy to color and that is an added benefit in many applications. Applications: Automotive and Aerospace Applications, Medical and Optical purposes, Electrical Wire and Cable Coverings. Tensile Strength Flexural Modulus Impact Strength Max Temp. Chem.
